Claims (1)

  1. В пассивной оптической системе дальней связи при upstream-передаче сигналов электрический сигнал несущей частоты модулируют по DPSK-методу, после чего модулированный таким образом электрический сигнал вызывает модуляцию интенсивности излучаемого света, при downstream-передаче сигналов излучаемый свет модулируют по интенсивности предпочтительно скремблированным NRZ-сигналом основной полосы. Сигнал несущей частоты выводят путем умножения частоты из восстановленного сигнала приемного такта децентрального устройства.
